Intramembranous ossification is the embryonic development of flat bones from an embryonic tissue called the mesenchyme. In this process, the mesenchyme first differentiates in to osteoblasts (bone–forming cell) which then begins to deposits osteoid (unmineralized matrix). Blood vessels invade the perichondrium, mesenchymal cells become osteoblasts, the perichondrium is converted into a periosteum and the inner layer produces bone. growth occurs by cell division of chondrocytes. in this region of the diaphysis, bone tissue has replaced most….

Stages of Intramembranous Ossification Results in the formation of cranial bones of the skull (frontal, perietal, occipital, and temporal bones) and the clavicles. 30. In the early stages of embryonic development, the embryo’s skeleton consists of fibrous membranes and hyaline cartilage. Osteogenesis, more commonly referred to as ossification, is a process by which new layers of bone tissues are laid by osteoblasts. Intramembranous ossification: Is the process of bone formation in which the mesenchyme differentiated directly into the bone, example, is the flat bones of the skull. The main difference between endochondral ossification and intramembranous ossification is that the endochondral ossification is the method of forming a bone through a cartilage intermediate while the intramembranous ossification directly forms the bone on the mesenchyme. Learn intramembranous ossification steps with free interactive flashcards. Bone formation: Ossification. Osteoblasts from the periosteum deposit a layer of compact bone over the spongy bone.
